Does every apartment block on Earth have a strange guy hanging around the stairs from time to time?

Pretty much

Oh, for sure. I see him every time I go out. Doesn't matter if it's noon or midnight. He's sitting on those stairs watching everyone go by.

Yes, there is a special Stairs Force that assigns its staff to apartment building.

Yes. It's part of the apartment experience...along with the crazy old lady...

No!

It only happens in luxury apartments.

Does in my neighborhood. I never leave after dark.

Yea I’m on duty right now

I believe they are called dealers and look outs.

The one's i've seen have been the building drug dealer

Dealers and scopers looking to do break ins...

Yes, it is part of the building code.
